Activity Trace0.10.0

Activity Trace lets you search your phone for notifications, screen content, and files you encountered previously, bringing them together in a private, on-device activity timeline. It creates a searchable memory of that activity so you can recover something you saw without manually revisiting each app. As an Android System Tools utility, it suits anyone who needs to find a past message, screen detail, or document across different parts of the device.

Search accepts ordinary keywords as well as time expressions such as “yesterday” and “last week.” Filters can narrow results by app or content type, using queries such as “in:signal” and “type:notification”; prefix matching, relevance ranking, and highlighted matches make results easier to scan. You can set a retention period, exclude individual apps, and view statistics showing how captured activity changes over time.

Activity Trace stores data encrypted at rest with SQLCipher AES-256-CBC and Android Keystore, while its privacy settings explain that blocked-app events and password fields are never captured. The interface offers system-default, light, dark, and OLED black themes, and Demo mode presents curated fictional activity without mixing it with real records. Version 0.10.0 adds the demo mode, theme selection, a relevance-and-recency search ranking, a privacy settings screen, and a welcome dashboard showing capture status with contextual setup guidance; it also improves encrypted backup and restore with integrity verification through a backup envelope.

It runs on Android 8.0 or later for arm64-v8a devices and is licensed under GPL-3.0-only. The application does not request Internet permission and provides no cloud service, account requirement, or telemetry; its data stays on the device, with no Google Play Services, proprietary dependencies, or AI and machine-learning components.
